sinh, sinhf, sinhl

Calculates the hyperbolic sine.

Syntax

double sinh(double x);
float sinhf(float x);
long double sinhl(long double x);
#define sinh(x) // Requires C11 or later

float sinh(float x);  // C++ only
long double sinh(long double x);  // C++ only

Parameters

x
Angle in radians.

Return value

The sinh functions return the hyperbolic sine of x. By default, if the result is too large, sinh sets errno to ERANGE and returns ±HUGE_VAL.

Input	SEH exception	_matherr exception
± QNaN, IND	None	_DOMAIN
`	x	≥ 7.104760e+002`

For more information about return codes, see errno, _doserrno, _sys_errlist, and _sys_nerr.

Remarks

Because C++ allows overloading, you can call overloads of sinh that take and return float or long double values. In a C program, unless you're using the <tgmath.h> macro to call this function, sinh always takes and returns double.

If you use the sinh macro from <tgmath.h>, the type of the argument determines which version of the function is selected. See Type-generic math for details.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.

Requirements

Routine	Required header (C)	Required header (C++)
sinh, sinhf, sinhl	<math.h>	<cmath> or <math.h>
sinh macro	<tgmath.h>

For more compatibility information, see Compatibility.

Example

// crt_sinhcosh.c
// This program displays the hyperbolic
// sine and hyperbolic cosine of pi / 2.
// Compile by using: cl /W4 crt_sinhcosh.c

#include <math.h>
#include <stdio.h>

int main( void)
{
   double pi = 3.1415926535;
   double x, y;

   x = pi / 2;
   y = sinh( x );
   printf( "sinh( %f ) = %f\n",x, y );
   y = cosh( x );
   printf( "cosh( %f ) = %f\n",x, y );
}

sinh( 1.570796 ) = 2.301299
cosh( 1.570796 ) = 2.509178
